I managed to break this in rust-lang#95449. I am not quite sure why this is the correct fix, but it doesn't break `doc --stage 0` and is strictly closer to the previous behavior. Previously, rustdoc would error with strange issues because of the mismatched sysroot: ``` error[E0460]: found possibly newer version of crate `std` which `rustc_span` depends on --> /home/jnelson/rust-lang/rust/compiler/rustc_lint_defs/src/lib.rs:14:5 | 14 | use rustc_span::{sym, symbol::Ident, Span, Symbol}; | ^^^^^^^^^^ | = note: perhaps that crate needs to be recompiled? = note: the following crate versions were found: crate `std`: /home/jnelson/rust-lang/rust/build/x86_64-unknown-linux-gnu/stage0/lib/rustlib/x86_64-unknown-linux-gnu/lib/libstd-ff9290e971253a38.rlib crate `std`: /home/jnelson/rust-lang/rust/build/x86_64-unknown-linux-gnu/stage0/lib/rustlib/x86_64-unknown-linux-gnu/lib/libstd-ff9290e971253a38.so crate `rustc_span`: /home/jnelson/rust-lang/rust/build/x86_64-unknown-linux-gnu/stage0-rustc/x86_64-unknown-linux-gnu/release/deps/librustc_span-ed11dce30c1766f9.rlib ```
…pnkfelix Only add codegen backend to dep info if -Zbinary-dep-depinfo is used I am currently migrating the cg_clif build system from using a binary linked to the codegen backend as rustc replacement to passing `-Zcodegen-backend` instead. Without this PR this would force cargo to rebuild the sysroot on any change to the codegen backend even if I explicitly specify that I want it to be preserved, which would make development of cg_clif a lot slower. If you still want to have changes to the codegen backend invalidate the cargo build cache you can explicitly specify `-Zbinary-dep-depinfo`. cc ``@eddyb`` as the codegen backend was initially added to the depinfo for rust-gpu.
…um, r=davidtwco Stabilize `derive_default_enum` This stabilizes `#![feature(derive_default_enum)]`, as proposed in [RFC 3107](rust-lang/rfcs#3107) and tracked in rust-lang#87517. In short, it permits you to `#[derive(Default)]` on `enum`s, indicating what the default should be by placing a `#[default]` attribute on the desired variant (which must be a unit variant in the interest of forward compatibility). ``````@rustbot`````` label +S-waiting-on-review +T-lang
Create (unstable) 2024 edition [On Zulip](https://rust-lang.zulipchat.com/#narrow/stream/213817-t-lang/topic/Deprecating.20macro.20scoping.20shenanigans/near/272860652), there was a small aside regarding creating the 2024 edition now as opposed to later. There was a reasonable amount of support and no stated opposition. This change creates the 2024 edition in the compiler and creates a prelude for the 2024 edition. There is no current difference between the 2021 and 2024 editions. Cargo and other tools will need to be updated separately, as it's not in the same repository. This change permits the vast majority of work towards the next edition to proceed _now_ instead of waiting until 2024. For sanity purposes, I've merged the "hello" UI tests into a single file with multiple revisions. Otherwise we'd end up with a file per edition, despite them being essentially identical. ```@rustbot``` label +T-lang +S-waiting-on-review Not sure on the relevant team, to be honest.
Check var scope if it exist Fixes rust-lang#92893. Added helper function to check the scope of a variable, if it doesn't have a scope call delay_span_bug, which avoids us trying to get a block/scope that doesn't exist. Had to increase `ROOT_ENTRY_LIMIT` was getting tidy error
Parse inner attributes on inline const block According to rust-lang#84414 (comment), inner attributes are intended to be supported *"in all containers for statements (or some subset of statements)"*. This PR adds inner attribute parsing and pretty-printing for inline const blocks (rust-lang#76001), which contain statements just like an unsafe block or a loop body. ```rust let _ = const { #![allow(...)] let x = (); x }; ```

only downgrade selection Error -> Ambiguous if type error is in predicate That is, we don't care if there's a TypeError type in the ParamEnv. Fixes rust-lang#95408
